Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27904, here are decompositions:
- 3 + 27901 = 27904
- 11 + 27893 = 27904
- 53 + 27851 = 27904
- 101 + 27803 = 27904
- 113 + 27791 = 27904
- 131 + 27773 = 27904
- 137 + 27767 = 27904
- 167 + 27737 = 27904
Showing the first eight; more decompositions exist.
